Server issue?

[Topic modified]

Hi,
That happened few hours ago and couldn’t find any solution 🙁

I have 4 wordpress site hosted by godaddy and I can’t open any of them. Each website show only codes of itself but not the pages.
I can’t even access wp-admin, just codes again, pls check: For example

I contacted Godaddy and they said its a migration of servers but no solution so far.
However I manually reinstalled wordpress via ftp one of the website but still same.

Is there anybody had same problem before or similar recently?
What do you think is it an attack or hacking issue?
